Hi, everybody, Use the “KISS” principle, USE whatever you have. If you spend your finite time looking at things that should OR could change from what you have on hand in an existing dwelling, you will never do anything.
The only thing you have of any value is the time you have left! Quit postulating what else might work better as what you have currently is what you need to work with. I looked out my kitchen window from 1981 until 1993 until an "hour walk on a piece of property" west of our home on a steeply sloped building site and “I saw and understood in that hour” an “IDEA” to create a means of receiving $750,000 in tax free money in the next three years.
USE what you have and be aware of your limited time. Now open your eyes and see what you can do to Passively Heat your home.
Look at your home as a “Piggy Bank” and spend $100 to create your very own “Passive Solar heating System” in your homes attic space. COMPLETE instructions are shown on Anachronism Page. Need further assistance, ASK.
